Object: FixedWidthBlock

Object: FixedWidthBlock

Use the FixedWidthBlock object to access channel data in a text file.

The data in this text file is not separated by a specific separator. The data is separated at a specific number of characters, which you specify in the CharacterCount property.

Note  The file pointer of the text file does not move when a FixedWidthBlock is read out.

The following example reads the values of a channel from a text file. Four characters of a text line correspond to one channel value. Each text line contains two channel values:

Dim oBlock: Set oBlock = File.GetFixedWidthBlock
Dim oChannelGroup: Set oChannelGroup = Root.ChannelGroups.Add("Channelgroup")

Dim oChn1 : Set oChn1  = oBlock.Channels.Add("Channel1", eI32)
oChn1.Formatter.CharacterCount = 4
oChn1.Formatter.SampleWidth = 2

Call oChannelGroup.Channels.AddDirectAccessChannel(oChn1)

oBlock.Position = File.Position
